Salt har­vest­ing

Focus-Science and Technology - - Q & A -

In Viet­nam’s Bạc Liêu Prov­ince, work­ers har­vest salt in the scorch­ing sun­shine. To get the salt, seawater is di­verted at into shal­low pools. As the wa­ter eva­po­rates, the salt is left be­hind. The work­ers gather the salt into piles us­ing a tool called a cào, be­fore send­ing it away for stor­age. They have to work fast – ac­cord­ing to res­i­dents, a down­pour of rain will dis­solve all the salt.
